The Middlesex County Ontario Provincial Police is reminding residents to Lock It or Lose It! The OPP would like to remind residents to take proactive steps to protect their property against theft. Always roll up your vehicle's windows, lock the doors and pocket the keys. If you have a garage, park inside. Make sure to keep vehicle and garage doors locked. If you must park outside, always park in a well-lit area. If your vehicle is equipped with a security system, remember to activate it.
